A multi-layered tube is composed of at least two layers formed of different resin compositions containing a polypropylene resin and at least one copolymer selected from the group consisting of hydrogenated block copolymers obtained by hydrogenation of block copolymers formed of a polymer block from a vinyl aromatic compound and an isoprene and/or butadiene polymer block and a hydrogenated copolymer obtained by hydrogenation of a copolymer from a vinyl aromatic compound and butadiene. The multi-layered tube can be used as a multi-layered tube for medical use which is excellent in flexibility and anti-kinking properties, further, which has durability against sterilization with high-pressure steam, which is free from generation of any toxic gas when incinerated, and which is excellent in hot solvent bonding or solvent adhesion to. other tube, and the like.

L'invention concerne un tube possédant une structure multicouches constituée d'au moins deux couches de composition différente et comprenant une composition de résine contenant une résine de polypropylène et au moins un copolymère choisi dans le groupe constitué des copolymères séquencés hydrogénés obtenus par hydrogénation d'un copolymère séquencé contenant une séquence polymère dérivée d'un composé aromatique vinylique et une séquence polymère d'isoprène et/ou de butadiène et de copolymères hydrogénés obtenus par hydrogénation d'un copolymère d'un composé aromatique vinylique et de butadiène. Le tube multicouches de l'invention présente une souplesse et des propriétés de résistance à l'entortillement excellentes et résiste à la stérilisation par vapeur haute pression. Ce tube ne génère aucun gaz nocif lors de son incinération, peut être soudé facilement à d'autres tubes par fusion ou au moyen d'un solvant et peut s'utiliser comme tube multicouches médical.
